“She hasn’t laughed harder in a very long time,” a source says. "She was embarrassed for him." Ouch!

Then again, Justin may have had this one coming. After all, the look Selena was referring to involves Justin wearing a yellow hat with metallic spikes jutting out of it, along with pink leopard-print sweats.

Also, he’s wearing a sweatshirt with drawings of brightly colored dollar bills, he has a gold watch on each wrist, and he’s wearing oversized glasses.

In other words, it’s basically a fashion don’t. Or maybe Justin’s fashion sense is just ahead of its time? But probably not.

So we’re wondering if Selena would often give him tips on what to wear while they were dating?

Needless to say, if you’re trying to think of a gift to give Selena for her next birthday, a yellow hat with metal spikes probably wouldn’t be the best choice. Now we know.
